Abstract

Endophytes, both bacterial and fungal, constitute an integral component of the leaf ecosystem. Here we argue that the respiratory metabolism of endophytes in the intercellular spaces of leaves could have a significant role in enhancing leaf photosynthesis by enriching the internal CO₂ concentration, especially in C3 plants.

Keywords: C3 plants; RuBisCO; fungal endophyte; photorespiration.
